When will be the day we will talk about root coz of this problem. HINDU. Why can not we have Hindu as religion but not as divider. Why do not we get rid of this castism and be one as hindu. Are you up to the challange? Come on BROTHERS & SISTERS (as said by VIVEKANAND) BE ONE. Kick casts out of our religion so the future generations will be proud to be called Hindu themselves.
Wake up Brothers & Sisters it is still not too late.
